Using these replacement pads is easy. Just remove the old pads from your Serina & Company bracelets and insert the new ones. For best results, place them in the designated pad holders. When the pads start to lose their scent, simply wash them with mild detergent and let them air - dry. They'll be ready to use again. Remember, don't use harsh chemicals or machine - dry the pads as this may damage the wool. With proper care, these pads will last you a long time and keep your bracelets smelling great.
